settlement letter

I have paid my account up and now they cannot even send me a paid up letter. I am told that they have sent it but I receive emails on the hour and yet their email fails to come through. I have gone to the extent of giving them 2 other emails and still not. Yet the consultants will call you at every hour for payment and now that I'm paid up, they can't even give me whats's rightfully mine. I don't even trust that they will update this on my ITC record
